Unlocked, Rooted, No Data connection on Red Pocket att.mnvo

Greetings,
Purchased a T-mobile samsung galaxy s 4.
I unlocked it. Tried to use Red Pocket mnvo and there is voice but no data.
So I rooted it and removed the T-mobile data usage apk and still no data.
I have spent hours trying to get data to work.
What more needs to be done to get this phone to operate on a Red Pocket or Straight Talk mnvo using AT&T towers?
I use the same settings that work in my other unlocked android phones and no luck.
What APK is responsible for preventing data to work?
Do I need to flash a new customized rom to get this to work?
Has anyone else gotton an AT&T mnvo to work on this T-Mobile Samsung Galaxy S 4?
I am still within my return period so I need to find a solution or send this phone back.
I was orginally going to use T-mobile because they seem to promise 4g here but when I got it I find out there is only 2g speeds where I live.

My post won't help .. but this is very interesting as I am going to do the same thing.
I'll definitely watch this thread.

Is any one else out there getting Data connection with other carries after unlocking and rooting there T-Mobile Samsung galaxy s 4?
Any ideas on the cause of no data?

Try changing the network operator or the mobile network and see if your not using tmobiles instead of at&t...

You need to go to mobile settings and change the apn to the network you are trying to connect to also I think the phone has to be network unlocked

unlock isn't network unlock?

I did change the network to the one I am trying to connect to.
Also, I went to cellunlocker and got an unlock code. I thought that unlocks the network? The data has worked on all my previous samsung galaxy's after using the unlock code except for this phone.
Please HELP someone!

[Q] LTE selection SM-T315

Hi
apologies in advance for this but its been driving me mad all day.
I recently got the 8.0 4G - Model number SM-T315 on stock up to date firmware from an O2 shop and have an active 4G sim but in Mobile Networks>Network mode I cannot select LTE/WCDMA/GSM as that option simply does not exist only GSM/WCDMA is available even when I am in an area I know has good coverage.
The sim will connect fine with another device though so not the network or sim.
Am I missing a setting somewhere or could I have a hardware problem or is the stock firmware just crap.
i don't want to flash it with a modded rom at the moment because of warranty although I have rooted it.
Any help appreciated

[Q] Can I make calls on the SM-T217S??

Hello,
I have searched throughly for my questions but didn't find anything unfortunately...
Will the tab 3 SM-T217S be able to make calls? I am talking regular calls not using apps that use data.
I live in a country where there is CDMA network provider and heard that there is no dialer on this tab which is important for me to programme the tab into my country's CDMA network provider.
I also came across a forum where it said the call functionality is there in the tab 3 but sprint has blocked it because the will only give you a plan with data not voice, so does that mean that if the SM-T217S gets programmed to another CDMA provider the call functionality can work normally??
I appreciate any help guys and thanks in advance!

Hey, i was about to purchase this to flash to IUSACELL Mexico, but instead went with the ATT version with SIM card because i have a better data plan with GSM provider than CDMA provider.
But i did some research prior going with the gsm tablet, and it appears you can flash it with DFS cdma soft, and of course if the new plan has DATA/VOICE it should work like a phone and sms and all that, providing you download a dialer and use an external hands free headset (i dont think it has a speaker like the GT3 8").
You wont find much information, all has to be done with trial and error.

will i be able to use a T-Mobile phone on AT&T network if i install AT&T firmware?

will i be able to use a T-Mobile phone on AT&T network if i install AT&T firmware?
i have a T-Mobile galaxy edge and want to use it on AT&T network and i was just wondering if i change the firmware will i be able to then use it on the AT&T mobile network?? or if anyone knows how i can do this please let me know how, from what i've learned the lock is due to a certain permission needed from the IMEI, i was also wondering if it can work by changing the IMEI??

Hello, and welcome to XDA!
In short, no and no. A SIM lock is due to something different. A firmware change from one carrier to another (in my experience) will not only not affect the SIM lock, but it can be disastrous for the phone. Changing the IMEI also has it's consequences.
I am connecting you to the forum your device experts can be found (T-Mo Galaxy Edge Q&A):
> T-Mobile Samsung Galaxy S6 Edge > T-Mobile Galaxy S6 Edge Q&A, Help & Troubleshooting
The experts will likely have some suggestions on how to SIM unlock.
Please note, to respond to replies, you will need to register for an XDA account.
Hope this helps, and good luck!
